How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 Generally, air ducts need to be cleaned every three to five years according to the National Air Duct Cleaners Association. Depending on a lot of factors—like your home’s location, how many pets you have, and how regularly your air filter has been swapped out, to name a few—you may require air duct cleaning more or less regularly. So, how can you know for sure when it’s time to have your ducts cleaned? There are certainly some revealing signs when it’s time. Look for these clues: Are your cold air returns caked with dust or pet hair? Is there an obstruction within your cold air return vent? Are your registers carrying out dust? When you look inside with a flashlight, can you see a collection of debris or pet fur? Have insects or rodents nestled in your ductwork?
